Radar system components to detect small and fast objects

Abstract

Small and fast objects, for example bullets of caliber 5 to 10 mm, fired from guns like AK-47, can cause serious problems to aircrafts in asymmetric warfare. Especially slow and big aircrafts, like heavy transport helicopters are an easy mark of small caliber hand fire weapons. These aircrafts produce so much noise, that the crew is not able to recognize an attack unless serious problems occur and important systems of the aircraft fail. This is just one of many scenarios, where the detection of fast and small objects is desirable. Another scenario is the collision of space debris particles with satellites

Tracking of Evasive Objects Using Bistatic Doppler Radar Operating in the Millimeter Wave Regime

“…As a result of such developments, the radar industry has seen great progress, mainly due to increased transmission frequencies from the S-band (2)(3)(4) to the W-band (75-110 GHz) and improved signal processing abilities. The increase in transmitting frequencies has enabled the detection of stealthy and fast targets, as a result of the reduced transmission wavelength that increases scattering resistance of targets [12], such as bullets [13,14], drone blades [15][16][17][18], missiles, and birds [19]. By improving dataprocessing capabilities, it has become possible to analyze additional information about the targets and, consequently, to classify them [20] as well as to recognize them and their actions [21].…”
